Curious minds might wonder why the LHC, which successfully ran at 7 TeV during the pp run of 2010 began the new year with proton collisions at a significantly less energy of 2.76 TeV. The fact is that this lower energy allowed experiments such as...

If you buy just about any LHC physicist a beer, and talk for a while, eventually you'll learn that he or she lives for the day when we make the next great discovery at this amazing machine. Many of them are placing their bets on finding the Higgs...

In our Universe today, quarks are always bound together by gluons to form "composite" particles such as protons and neutrons. The Quark-Gluon Plasma, or QGP, often described as a soup-like medium, is a hot, dense state in which these quarks and...

The CMS experiment has made several unique measurements using data from LHC collisions of lead nuclei (PbPb, November 2010) at centre-of-mass energies of 2.76 TeV per nucleon pair. Phenomena measured for the first time in nucleus-nucleus collisions...
